[Zope] DTML-In with date/time filter

[Jonathan]

You are going to have to loop thru the documents and use 'getProperty' to 
access the date property field on the document. Then you will need to 
compare the date value (the Zope Book V2.6 has a good description of 
dates/time usage) to see if it is in the range you need.  You could use a 
python script to do this loop/compare and return a list of document ids 
which you could then display via your DTML-in stmt.

If you have a lot of documents this could be a very expensive approach.  You 
might want to have a look at ZCatalog.

Hello Andreas,
I use this code in a Python script and call this script within a DTML-IN 
statement. What I need is a script to get only items with a date in the 
future, today or in the past.  The objects are DTML Documents with a date 
property field.

Using "return" in DTML does not make sense. Writing such code in DTML
is bad-style. Use Pythonscript for this code and call the script from
DTML (btw. better user ZPT).

What does that mean?
